Can someone help me and complete this simple polynomial program(can be demonstrated using linked lists);

```
public class Polynomial {
/* Constructs a new polynomial of degree zero */
public Polynomial() {
}
/* Returns an integer representing the coefficient
* of the x^power term
*/
int getCoefficients(int power) {
}
/* Sets the coefficient of the x^power term to coef. */
void setCoefficients(int coef, int power) {
}
/* Returns the String representation of the polynomial.
* For example, a polynomial can be represented as either
* 3 * x^2 + 2 * x + 1 or
* 3x^2 + 2x + 1
* Any term whose coefficient is zero should not appear
* in the string unless the polynomial has only a single
* constant term of zero.
*/
public String toString() {
}
/* Evaluates the polynomial for the value x and returns
* the result p(x).
*/
double evaluate(double x) {
}
/* Add to this polynomial the polynomial "other" and
* return the resulting polynomial.
*/
Polynomial add(Polynomial other) {
}
}
```
